5 / 11 page Pin Functions Pin No. Symbol Equivalent circuit Function 1, 2 32, 33 IN1, IN2 IN3, IN4 to Actuator control signals for each driver: IN1: Focus, IN2: Tracking, IN3: Spindle, IN4: Sled. These signals are input from the ASP (DSP). 30 ASPREF Control reference signal input pin for each driver. This signal is input from the ASP (DSP). 43, 42 41, 40 38, 37 36, 35 OUT1 +,1– OUT2 +,2– OUT3 +,3– OUT4 +,4– Focus coil actuator drive output pins. Tracking coil actuator drive output pins. Spindle motor drive output pins. Sled motor drive output pins. (Each channel includes built-in spark killer diodes.) 3 31 VOUT1 VOUT2 Power supply pins for the H bridge driver. VOUT1 is for the focus/tracking group and VOUT2 is for the spindle/sled group. Maximum value + α (α : saturation voltage of upper/lower output Tr) of each 2-channel control output is set by external PWM step-down circuit. 4VCD Power supply for the actuator driver controller, maximum value circuit for PWM, and sled controller. 5 CHGDRV Constant current value of each Constant-current circuit which changes with the input of CH1 through 4. (3 mA max) Base drive output pin for the external NPN-Tr for the battery pulse charging circuit. 9 EXTDRV Base drive output pin for the external step-down NPN-Tr used when external voltage input is applied. 14 DNB-1 Base drive output pin for the PNP-Tr for the step-down PWM that generates the power supply for the H bridge driver that drives the focus/tracking group actuators. (Open when there is one H bridge power supply.) 15 DNB-2 Base drive output pin for the PNP-Tr for the step-down PWM that generates the power supply for the H bridge driver that drives the spindle/sled group actuators. (DNB-2 becomes the drive pin when there is one H bridge power supply.) 17 ASPDRV Base drive output pin for the external NPN-Tr for the step-up circuit that sets the external voltage for the DSP. 24 APCDRV Base drive output pin for external NPNTr for the laser diode APC power supply.
